Looking at a 2015 Denali XL 4x4 with the 6.2 and a 6-speed transmission (build date of 9/14 so from what I have read 6-speed is correct). Has 161K on it and with a every service record. Question about the 6.2. At 160K the CarFax states "engine valve spring(s) replaced" and then 1,000 miles later they traded it in. They owned it for roughly 100K miles. I am planning on calling the shop on Monday that did the valve springs and seeing if I can find anything else out. (i.e., did they replace all or just one)
My question to anyone with more knowledge about these engines than me: Is it worth calling the shop or should I just keep looking?
I have read so much about the valve springs and lifters (and don't know enough about engines) that I'm confused if it's good they had the valve springs replaced (if they had all replaced) or if it's a sign of things to come.
Also, from what I have read the 6-speed seems to be a reliable transmission. At 118k they took it to a GM dealer and had the "transmission serviced" so I'm going to call them and see if they can/will tell me what that means. That's they only transmission related service shown so it will need a transmission fluid exchange (flush not recommended from what I have read, not even BG?)
